What is the most common cause of dermatitis?

The most influential factor relates to dental professionals not caring for their hands properly. After repeated exposure to soaps and chemicals, clinicians often don’t follow the steps needed to protect their hands. For example, when soap is not rinsed off the hands and then the gloves go on, the hands perspire, reactivating the soap left on the hands, causing irritation. A reddened area can develop with itching. This irritation eventually breaks epithelium, thereby initiating dermatitis. This is a nonspecific dermatitis caused by contact with substances that physically or chemically break down or damage the skin. This non-immunological adverse reaction is the most common form of observed hand dermatitis.
